Bonaprene has a very flexible polyurethane, PU, sheet strip & block manufacturing process. If the customerís polyurethane sheet, strip or block part is within the sizes of the Hot Plate Tableís maximum widths and lengths there is usually no tooling cost. The thickness is only restricted by weight - so there is an upper limit - but only on the very largest thickest parts.
